TECHNICAL FIELD

The disclosure relates to the field of communications, and moreparticularly to a method and device for information transmission.

BACKGROUND

In a long-term evolution-based licensed-assisted access (LAA-LTE)system, services are provided for a terminal device by taking a carrieron a licensed spectrum as a primary carrier and taking a carrier on anunlicensed spectrum as a secondary carrier. A communication devicefollows a “listen before talk (LBT)” principle on an unlicensedspectrum, namely the communication device, before sending a signal on achannel of the unlicensed spectrum, is required to monitor the channelat first, the communication device may send the signal only when achannel monitoring result is that the channel is idle, and if thechannel monitoring result of the communication device for the channel ofthe unlicensed spectrum is that the channel is busy, the communicationdevice may not send the signal.

Since data transmission of a communication device is opportunistic, datamay be transmitted only when LBT succeeds and no data may be transmittedwhen LBT fails, a network device and a terminal device in a cell servedby the network device are required to know when the opposite partystarts data transmission and stops data transmission so as to implementcorrect data communication between the terminal device and the networkdevice.

When a new radio (NR) technology is applied to an unlicensed spectrum,multiple subcarrier spacings and broadband transmission are supported.

In S210, a network device determines a first time-domain resourceavailable on a first carrier, the first time-domain resource being atime-domain resource in a first downlink transmission burst.

In S220, the network device sends first information to a terminal devicethrough the first time-domain resource on the first carrier. The firstinformation is used to indicated that time-domain resource informationof a first transmission burst needs to be determined according to afirst subcarrier spacing.

Therefore, the network device may send the first information to theterminal device through the time-domain resource in the firsttransmission burst on the first carrier and indicate a determinationmanner for the time-domain resource information of the firsttransmission burst (which may include, for example, an uplinktransmission burst and/or a downlink transmission burst) through thefirst information, and in such a manner, the terminal device and thenetwork device may reach an agreement on a time-domain resource positionof the first transmission burst, and correct data communication betweenthe terminal device and the network device may be implemented.

It is to be noted that, in the embodiment of the disclosure, the firstcarrier is an unlicensed carrier, namely the first information may beused to indicate a determination manner for time-domain resourceinformation of a transmission burst on the unlicensed carrier.

Optionally, in the embodiment of the disclosure, the first time-domainresource used for sending the first information may be a time-domainresource configured by the network device to transmit a downlink controlchannel in the first downlink transmission burst, for example, atime-domain resource in a Control Resource Set (CORESET).

It is to be understood that, in the embodiment of the disclosure, adownlink transmission burst may be defined as one or more time units forcontinuous transmission of the network device, and similarly, an uplinktransmission burst may be defined as one or more time units forcontinuous transmission of the terminal device. One time unit may be oneor more subframes, may also be one or more slots, and may also be one ormore mini-slots or symbols, etc. A starting time unit and/or ending timeunit of a downlink transmission burst or an uplink transmission burstmay be a complete time unit and may also be part of a time unit, etc.There are no limits made thereto in the embodiment of the disclosure.

Optionally, in the embodiment of the disclosure, the time-domainresource information may include at least one of: a starting position;an ending position; a channel occupancy duration; or, a slot format; or,the time-domain resource information may also be other informationcapable of reflecting the time-domain resource position. There are nospecial limits made thereto in the embodiment of the disclosure.

For example, the time-domain resource information of the firsttransmission burst may include a starting position, for example, astarting symbol or a starting slot, of the first transmission burst.

Or, the time-domain resource information of the first transmission burstmay include an ending position, for example, an ending symbol or anending slot, of the first transmission burst.

Or, the time-domain resource information of the first transmission burstmay include a channel occupancy duration in the first transmissionburst, i.e., a duration, for example, a number of subframes or a numberof slots, occupied by channel transmission in the first transmissionburst.

Or, the time-domain resource information of the first transmission burstmay include the slot format of the first transmission burst. Forexample, the slot format of the first transmission burst may indicateslot formats in one or more slots in a bitmap manner; or, the slotformat of the first transmission burst may also indicate the number ofdownlink symbols and/or the number of uplink symbols in a slot; or, theslot format of the first transmission burst may indicate a slot formatindex in a slot, and the slot format index may be used to indicate aspecific slot format. An indication manner for the slot format of thefirst transmission burst is not specially limited in the embodiment ofthe disclosure.

Optionally, in the embodiment of the disclosure, the first transmissionburst may include at least one of the first downlink transmission burston the first carrier or a first uplink transmission burst on the firstcarrier, namely the network device may not only indicate time-domainresource information of the downlink transmission burst on the firstcarrier through the first indication but also indicate time-domainresource information of the uplink transmission burst on the firstcarrier through the first information, so that the terminal device andthe network device may reach an agreement on time-domain resourcepositions of the downlink transmission burst and/or uplink transmissionburst on the first carrier, and correct data communication between theterminal device and the network device may be implemented.

Optionally, in some embodiments, a frequency-domain resource where thefirst uplink transmission burst on the first carrier is located at leastpartially overlaps with a frequency-domain resource where the firstdownlink transmission burst on the first carrier is located. Forexample, the first downlink transmission burst on the first carrier andthe first uplink transmission burst on the first carrier may be on thesame sub-band of the first carrier.

It is to be understood that, in the embodiment of the disclosure, thefirst subcarrier spacing used for determining the time-domain resourceinformation of the first transmission burst may be a subcarrier spacingdefined by a communication system, or, the first subcarrier spacing maybe a subcarrier spacing configured by the network device, or, the firstsubcarrier spacing may also be a subcarrier spacing used for the networkdevice to transmit downlink control information, etc. There are nolimits made thereto in the embodiment of the disclosure.

Optionally, a size of the first subcarrier spacing is less than or equalto a size of a subcarrier spacing used for physical channel transmissionon the first carrier.

An indication manner for the first information will be described belowin detail.

First embodiment: the first information may further be used to indicatethat time-domain resource information of a second transmission burstneeds to be determined according to the first subcarrier spacing, andthe second transmission burst may include at least one of the following:

a second downlink transmission burst on the first carrier;

a second uplink transmission burst on the first carrier;

a third downlink transmission burst on a second carrier; or

a third uplink transmission burst on the second carrier.

A frequency-domain resource where the second transmission burst islocated does not overlap with a frequency-domain resource where thefirst transmission burst is located.

That is, the first information may not only indicate that thetime-domain resource information of the first transmission burst needsto be determined according to the first subcarrier spacing but alsoindicate that the time-domain resource information of the secondtransmission burst needs to be determined according to the firstsubcarrier spacing, namely the network device may indicate that both thetime-domain resource information of the first transmission burst and thetime-domain resource information of the second transmission burst needto be determined according to the same subcarrier spacing. According tofrequency-domain positions of the first transmission burst and thesecond transmission burst, the following two scenarios may be included.

A first scenario: the first transmission burst and the secondtransmission burst may be on different sub-bands of the same carrier.For example, the first carrier may include a first sub-band and a secondsub-band, the first transmission burst may be on the first sub-band ofthe first carrier, and the second transmission burst may be on thesecond sub-band of the first carrier. Specifically, the firsttransmission burst may include the first uplink transmission burstand/or first downlink transmission burst on the first sub-band of thefirst carrier, and the second transmission burst may include the seconduplink transmission burst and/or second downlink transmission burst onthe second sub-band of the first carrier.

A second scenario: the first transmission burst and the secondtransmission burst may be on different carriers. For example, the firsttransmission burst is on the first carrier, and the second transmissionburst is on the second carrier. The first transmission burst may includethe first uplink transmission burst and/or first downlink transmissionburst on the first carrier, and the second transmission burst mayinclude the third downlink transmission burst and/or third uplinktransmission burst on the second carrier. Optionally, the third downlinktransmission burst on the second carrier and the third uplinktransmission burst on the second carrier may be on the same sub-band ofthe second carrier.

To sum up, in the first embodiment, the first information transmitted onthe first carrier may be used to indicate that time-domain resourceinformation of transmission bursts on at least two sub-bands of thefirst carrier needs to be determined according to the same subcarrierspacing, i.e., the first scenario. Time-domain resource positions of thetransmission bursts on the at least two sub-bands may be the same, andunder this condition, the first information may only indicate only onepiece of time-domain resource information. Or, the time-domain resourcepositions of the transmission bursts on the at least two sub-bands maybe different, and under this condition, the first information may beused to indicate the time-domain resource position of the transmissionburst on each of the at least two sub-bands.

Or, the first information transmitted on the first carrier may not onlybe used to indicate the determination manner for the time-domainresource information of the first transmission burst on the firstcarrier but also be used to indicate a determination manner fortime-domain resource information of the second transmission burst onanother carrier, for example, the second carrier. That is, the firstinformation may be used to indicate determination manners fortime-domain resources of transmission bursts on at least two carriers.The subcarrier spacing used for determining the time-domain resourceinformation of the first transmission burst on the first carrier and thesubcarrier spacing used for determining the time-domain resourceinformation of the second transmission burst on the second carrier maybe the same, i.e., the second scenario.

Optionally, in the embodiment of the disclosure, the second carrier maybe an unlicensed carrier different from the first carrier.

In a specific implementation of the first embodiment, the firstinformation is used to indicate that a first ending position of thefirst transmission burst needs to be determined according to the firstsubcarrier spacing, and the first information is further used toindicated that a second ending position of the second transmission burstneeds to be determined according to the first subcarrier spacing, aninterval between the first ending position and the second endingposition being less than or equal to a first preset value.

Optionally, in some embodiments, the first preset value may be 1 ms.

For example, in the first scenario, ending positions of the transmissionbursts on the at least two sub-bands of the first carrier may bedifferent, and under this condition, a time interval between the endingpositions of the transmission bursts on the at least two sub-bands is nomore than the first preset value.

Or, in the second scenario, the ending position of the transmissionburst on the first carrier and the ending position of the transmissionburst on the second carrier may also be different, and under thiscondition, a time interval between the ending position of thetransmission burst on the first carrier and the ending position of thetransmission burst on the second carrier is no more than the firstpreset value.

Second embodiment: the first information may further be used to indicatethat time-domain resource information of a third transmission burstneeds to be determined according to a second subcarrier spacing, and thethird transmission burst includes at least one of the following:

a fourth downlink transmission burst on the first carrier;

a fourth uplink transmission burst on the first carrier;

a fifth downlink transmission burst on the second carrier; or,

a fifth uplink transmission burst on the second carrier.

A frequency-domain resource where the third transmission burst islocated does not overlap with the frequency-domain resource where thefirst transmission burst is located.

That is, the first information may not only be used to indicate that thetime-domain resource information of the first transmission burst needsto be determined according to the first subcarrier spacing but also beused to indicate that the time-domain resource information of the thirdtransmission burst needs to be determined according to a subcarrierspacing that is not the first subcarrier spacing, for example, thesecond subcarrier spacing. According to frequency-domain positions ofthe first transmission burst and the third transmission burst, thefollowing two scenarios may be included.

A third scenario: the first transmission burst and the thirdtransmission burst may be on different sub-bands of the same carrier.For example, the first carrier may include the first sub-band and thesecond sub-band, the first transmission burst may be on the firstsub-band of the first carrier, and the third transmission burst may beon the second sub-band of the first carrier. That is, the firstinformation may be used to indicate that time-domain resourceinformation of transmission bursts on different sub-bands of the firstcarrier needs to be determined according to different subcarrierspacings. For example, the first transmission burst may include thefirst uplink transmission burst and/or first downlink transmission burston the first sub-band of the first carrier, and the third transmissionburst may include the fourth uplink transmission burst and/or fourthdownlink transmission burst on the second sub-band of the first carrier.

A fourth scenario: the first transmission burst and the thirdtransmission burst may be on different carriers. For example, the firsttransmission burst is on the first carrier, and the third transmissionburst is on the second carrier. The first transmission burst may includethe first uplink transmission burst and/or first downlink transmissionburst on the first carrier, and the third transmission burst may includethe fifth downlink transmission burst and/or fifth uplink transmissionburst on the second carrier. Optionally, the fifth downlink transmissionburst on the second carrier and the fifth uplink transmission burst onthe second carrier may be on the same sub-band of the second carrier.

To sum up, in the second embodiment, the first information transmittedon the first carrier may be used to indicate that time-domain resourceinformation of transmission bursts on different sub-bands of the firstcarrier needs to be determined according to different subcarrierspacings, i.e., the third scenario. Time-domain resource positions oftransmission bursts on different sub-bands may be different, forexample, there are different ending positions of downlink transmissionbursts on different sub-bands for the network device, so that thenetwork device may release idle frequency-domain resources when a loadof the network device is reduced, which is favorable for increasing theutilization rate of frequency-domain resources.

Or, the first information transmitted on the first carrier may be usedto indicate that time-domain resource information of transmission burstson different carriers needs to be determined according to differentsubcarrier spacings, i.e., the fourth scenario. Time-domain resourcepositions of transmission bursts on different sub-bands may also bedifferent, for example, there are different ending positions of downlinktransmission bursts on different carriers for the network device, sothat the network device may release the idle frequency-domain resourceswhen the load of the network device is reduced, and the utilization rateof the frequency-domain resources may further be increased.

Optionally, in a specific implementation of the second embodiment, thefirst information is used to indicate that the first ending position ofthe first transmission burst needs to be determined according to thefirst subcarrier spacing, and the first information is further used toindicate that a third ending position of the third transmission burstneeds to be determined according to the second subcarrier spacing, aninterval between the first ending position and the third ending positionbeing less than or equal to a second preset value.

For example, in the third scenario, the first ending position of thefirst transmission burst may be a first ending position of thetransmission burst on the first sub-band of the first carrier, and thethird ending position of the third transmission burst may be a thirdending position of the transmission burst on the second sub-band of thefirst carrier. Or, in the fourth scenario, the first ending position ofthe first transmission burst may be a first ending position of thetransmission burst on the first carrier, and the third ending positionof the third transmission burst may be a third ending position of thetransmission burst on the second carrier. The first ending position andthe third ending position may be different, and under this condition, atime interval between the first ending position and the third endingposition is no more than the second preset value.

Optionally, in some embodiments, the second preset value may be 1 ms.

To sum up, in the first embodiment and the second embodiment, the firstinformation transmitted on the first carrier may be used to indicate thedetermination manner for the time-domain resource information of thedownlink transmission burst and/or uplink transmission burst on thefirst carrier and may further be used to indicate the determinationmanner for time-domain resource information of downlink transmissionbursts and/or uplink transmission bursts on at least two sub-bands ofthe first carrier. The time-domain resource information of the at leasttwo sub-bands is determined according to the same subcarrier spacing ordetermined according to different subcarrier spacings. Or, the firstinformation may further be used to indicate a determination manner fortime-domain resource information of a downlink transmission burst and/oruplink transmission burst on another carrier, for example, the secondcarrier. The time-domain resource information of the transmission burston the second carrier and the time-domain resource information of thetransmission burst on the first carrier are determined according to thesame subcarrier spacing or determined according to different subcarrierspacings. There are no limits made thereto in the embodiment of thedisclosure.

Optionally, in some embodiments, the method 200 may further include thefollowing operation.

The network device transmits a downlink physical channel according to athird subcarrier spacing.

The third subcarrier spacing may be different from the first subcarrierspacing, namely the subcarrier spacing used for transmitting thedownlink physical channel may be different from the subcarrier spacingused for determining the downlink transmission burst. That is, after thetime-domain resource information of the downlink transmission burst isdetermined according to the first subcarrier spacing, during practicaldata transmission, the downlink physical channel may be transmittedaccording to the third subcarrier spacing different from the firstsubcarrier spacing. Of course, the network device may also transmit thedownlink physical channel according to the first subcarrier spacing.There are no specific limits made thereto in the embodiment of thedisclosure.

For example, as illustrated in FIG. 3 , the first subcarrier spacing is,for example, 15 kHz, and the network device may determine thetime-domain resource information of the first downlink transmissionburst, for example, a channel occupancy duration in the first downlinktransmission burst or the ending position, according to 15 kHz. Duringpractical data transmission on the time-domain resource corresponding tothe first downlink transmission burst, the network device, after channeldetection is successful (for example, LBT is successful or Clear ChannelAssessment (CCA) is successful), may transmit the downlink physicalchannel according to a subcarrier spacing the same as or different fromthe first subcarrier spacing (for example, according to one or moresubcarrier spacings in 15 kHz, 30 kHz and 60 kHz).

For another example, as illustrated in FIG. 4 , the first carrier mayinclude a sub-band #1 and a sub-band #2, the first information may beused to indicate that the time-domain resource information of the firstdownlink transmission burst corresponding to the sub-band #1 needs to bedetermined according to the first subcarrier spacing (for example, 15kHz) and may further be used to indicate that the time-domain resourceinformation of the second downlink transmission burst corresponding tothe sub-band #2 needs to be determined according to the secondsubcarrier spacing (for example, 30 kHz), and the ending positions ofthe downlink transmission bursts on the sub-band #1 and the sub-band #2may be different. Optionally, a time interval between the endingpositions may be less than or equal to the second preset value.

During practical data transmission in the sub-band #1 and the sub-band#2, the network device, after successful channel detection (for example,successful LBT or successful CCA) on the sub-bands, may transmit thedownlink physical channel in the sub-band #1 according to a subcarrierspacing the same as or different from the first subcarrier spacing (forexample, the downlink physical channel may be transmitted on thetime-domain resource of the first downlink transmission burst in thesub-band #1 according to one or more subcarrier spacings in 15 kHz, 30kHz and 60 kHz) and transmit the downlink physical channel in thesub-band #2 according to a subcarrier spacing the same as or differentfrom the second subcarrier spacing (for example, the downlink physicalchannel may also be transmitted on the time-domain resource of thesecond downlink transmission burst in the sub-band #2 according to oneor more subcarrier spacings in 15 kHz, 30 kHz and 60 kHz).

Optionally, in some embodiments, 5220 may specifically include thefollowing operations.

The network device sends the first information to the terminal deviceaccording to the first subcarrier spacing through the first time-domainresource on the first carrier; or,

the network device sends the first information to the terminal deviceaccording to a fourth subcarrier spacing through the first time-domainresource on the first carrier.

The first subcarrier spacing is different from the fourth subcarrierspacing, that is, the subcarrier spacing used for sending the firstinformation and the subcarrier spacing used for determining the downlinktransmission burst may be the same and may also be different.Specifically, the network device may determine a downlink controlresource used for sending the first information, and the downlinkcontrol resource may be determined according to the first subcarrierspacing and may also be determined according to another subcarrierspacing, which is not limited in the embodiment of the disclosure. Thedownlink control resource is the abovementioned first time-domainresource. Furthermore, the network device may send the first informationon the downlink control resource on the first carrier according to thefirst subcarrier spacing or a subcarrier spacing that is not the firstsubcarrier spacing, for example, the fourth subcarrier spacing.

Therefore, according to the method for information transmission in theembodiment of the disclosure, the network device may indicate adetermination manner for a time-domain resource position of atransmission burst on an unlicensed carrier through indicationinformation. Optionally, if the unlicensed carrier includes at least twosub-bands, the indication information may further be used to indicatethat time-domain resource information of transmission bursts in the atleast two sub-bands needs to be determined according to the samereference subcarrier spacing (i.e., the first subcarrier spacing) orindicate that the time-domain resource information of the transmissionburst in each sub-band needs to be determined according to anindependent reference subcarrier spacing. Or, the first information mayfurther be used to indicate that time-domain resource information oftransmission bursts on at least two carriers needs to be determinedaccording to the same reference subcarrier spacing or may further beused to indicate that the time-domain resource information of thetransmission burst on each carrier needs to be determined according toan independent reference subcarrier spacing. Therefore, the terminaldevice and the network device may reach an agreement on time-domainresource positions of uplink transmission bursts and/or downlinktransmission bursts, and normal data communication between the networkdevice and the terminal device may be implemented.
